According to the researches, the performance of masonry buildings in severe earthquakes is very weak and on the other hand, there is no comprehensive research regarding a suitable strategy for strengthening of these buildings. The use of shot-Crete concrete cover on the masonry walls building is one of the solutions, but due to the fact that this solution is a precious price method, a modern and low cost method is needed. In this paper, for the numerical simulation of a masonry wall, ABAQUS software with EXPLICIT method is selected and in order to achieve a new improvement method, first, reinforcement models of masonry wall made by hollow clay blocks using nonlinear incremental loads has been investigated and then the best adapted model is chosen.
The results of study (before and after improvement) of application of two Bam and Manjil seismic accelerometer data on a school model and simulation of them by finite element method shows the effectiveness of new method for improving the performance with featuring lower cost.
